COMBINED SCREW HOLDER AND DRIVER.

SPECIFICATION forming part of Letters Patent No. 351,751, dated November 2, 1886 l Application. filed March 15, 1886. Serial No. 195,344. (No model.) i

i a citizen of the United States, residing at lumbia City, in the county of Whitley and State of Indiana, have invented a new and useful Serew-Holder and Screw-Driver Oombined, of which the following is a specification. a

Myinvention relates to the construction and operation of a combined screw holder and driver; and the object of my invention is to provide a means by which a screw may be ef- :fectively and securely held on the end of the blade ofa screw-driver while the screw is being placed in position for insertion and while it is being driven where desired, the screw being thus held without the necessity of touching it with the hand, thereby enabling the operator to set and insert screws in places where it is or might be very difficult to set or insert them in the usual way without the use of my combined screw holder and driver herein described. v

The mechanism by which my object is attained is illustratedin the accompanyingdrawings, in which V Figure 1 is a general detailed view, in perspective, of the device, showing the screw holder and driver with a screw held in position on the point of the driver-blade ready for use. Fig. 2 shows the device with the clamp or jaws of the holder drawn back from the point of and onto the body of the blade of the driver, so that the latter may be freely used as an ordinary driver. Fig. 3 shows the driverblade drawn back, leaving the jaws open to receive a screw.

Similar letters refer to similar out the several views.

A, Fig. 1, is the handle of the screw-driver, and B theblade, both made in about the usual form.

D and D show two stops or rings firmly attached to orfor ned from blade B, and between these two stops the band or collar E moves freely around the blade 13. From band E projects the loop or slide F, through which the two equal parts of the holder H H slide freely, the two parts constituting a single piece of metal, which is bent in a free loop around the blade of the driver, as shown at J. The two parts throughso shaped as to form the jaws K K, (shown as holding-screw S,)andthetwo halves aresprung apart from where they form the loop J, in such a manner that as they are jointly drawn through slide F toward handle A the jaws KK are brought together by the pressure of slide F simultaneously on both parts H H, as shown. After a screw has been driven far enough to be considered safely fixed in its position, a backward pull on the handle A ,withdraws the point of blade B from the slot in the screwhead, and at the same time moves loop J tohalves of the holder HH have their outer ends I ward stop D, and as the parts H H of the hold- .65

jaws for practical use, as before stated.

My invention is specially adapted for use in cases where the places for inserting the screws are difficult of access, and if the ma terial be wood, and no hole has been made in it for the screw to be started in, a slight blow with a hammer onthe outer end of handle A. will usually set the screw for insertion without further trouble.

All the various parts of my invention may be made as heavy andstrong as may be desired. The jaws may be made wide or narrow, as may be deemed advisable,and yetthegeneral plan of construction and operation remain the same in principle as herein set forth.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-- The combination, with a screw-driver having fast rings D D and intermediate loose band, E,.provided with guide-loop F, of the screw-holder H, having loop J at one end and at the otherthe spring-jaws K K, all arranged and adapted to be used as described. \VILLIAM E. DOUGLAS.
